The invention provides a pretreatment method and device for organic pollutants in soil, and the method comprises the following steps: dissolving a to-be-detected sample in a constant-volume first centrifugal tube, sequentially adding an extraction solvent and an extraction reagent into the dissolved sample, dissolving, adding the extraction solvent and adding the extraction reagent, and uniformly mixing respectively, extracting to obtain an extracting solution; carrying out purification treatment on the extracting solution in a second centrifugal tube; filtering the purified solution obtained by purification treatment by using a 0.22 [mu] m filter membrane, and adding 1mL of the solution into an internal standard to obtain a solution to be detected; the method comprises the following steps: preparing a standard solution, determining the standard solution to obtain a standard curve, and obtaining the organic pollutant content of a to-be-detected sample based on the to-be-detected solution and the obtained stan
